12:29 <janrinze> Out of curiosity, who is running Linux on a Snapdragon X-Elite ?

12:37 chrisl has quit [Ping timeout: 480 seconds]

12:44 * JensGlathe[m] on a HP Omnibook X14, and on "angrybox" Snapdragon Dev Kit

12:45 <Jasper[m]> @janrinze many, it's doing fairly well from what I gather from the chatter here.

14:27 <kuruczgy> from what I heard the Ubuntu concept image is also very good, and I also heard of some people running Fedora

14:48 <janrinze> Thanks for the replies. Considering the price tag on those laptops I think I will wait a bit before taking the plunge. From what i've heard there will be more main-line kernel changes upcoming and also at some point we will see hardware accelerated graphics too.

14:49 <JensGlathe[m]> wdym hardware-accelerated graphics

14:50 <JensGlathe[m]> we have this for a long time now, also on x1e

14:52 <janrinze> JensGlathe[m]: Oh, I did not know that. thanks.

14:57 <jhovold> janrinze: this should give you an indication of where things stand:

14:59 <janrinze> jhovold: thanks! i'll keep an eye out on that page.

18:28 SpieringsAE has joined #aarch64-laptops

18:29 <SpieringsAE> So I sent in this patch, which was then given a <reviewed by> tag, but then I found a little mistake I made, I asume I should drop the <reviewed by> tag for the next version right?

18:31 <SpieringsAE> It was given by Dmitry Baryshkov, I don't know if he is in here too

18:32 <konradybcio> SpieringsAE: he is: lumag

18:33 alfredo has quit [Quit: alfredo]

18:34 <SpieringsAE> okay, I will wait for an answer from him before I send in V5

18:34 <travmurav[m]> SpieringsAE: I think it depends on how "little" the mistake is, i.e. if it's just some typo, can keep the r-b; if it's something actually significant then better drop the tags on the modified patch

18:35 <SpieringsAE> its a bad pinctrl definition in a node

18:35 <travmurav[m]> obviously just dropping tags and noting that as a changelog item is the safest approach

18:35 <travmurav[m]> hm

18:35 <SpieringsAE> I had pinctrl-0 and pinctrl-1

18:35 <SpieringsAE> but should only have been pinctrl-0

18:36 <SpieringsAE> just with two pinctrl references inside

18:37 <travmurav[m]> oh yeah that's a mistake but I'd keep the r-b in that case and just send a next rev tbh

18:37 * travmurav[m] wonders why(/if) dtbs_checks didn't(couldn't) catch this

18:37 <SpieringsAE> its in this one https://lore.kernel.org/all/20241125-asus_qcom_display-v4-3-61a4da162406@hotmail.com/ in the wcn7850_pmu node

18:38 <SpieringsAE> I really need to fix a .venv so I can properly do that

18:38 <travmurav[m]> yeah I've guessed already :P

18:38 <SpieringsAE> Guess that will be my project for tomorrow

18:38 <SpieringsAE> I shall wait then anyway give the for sure once over

18:39 <travmurav[m]> SpieringsAE: hm, one thing is I think you'd write it <&foo>, <&bar> in that case

18:39 <travmurav[m]> <blah blah> groups relevant items (i.e. a phandle + it's info cells)

18:39 <SpieringsAE> hmm okay, I will try to find some more info about it

18:40 <travmurav[m]> (there is no difference to the de-facto compiled dtb but just style/semantics)

18:41 <travmurav[m]> SpieringsAE: https://elixir.bootlin.com/linux/v6.12.1/source/arch/arm64/boot/dts/qcom/x1e80100.dtsi#L745 this is a good showcase I guess - some clocks have #cells=0 and some #cells=1

18:42 <travmurav[m]> and pinctrl config is implied 0 cells

18:48 <SpieringsAE> found a dts that both <&1 &2> and <&1>, <&2> lol

18:48 <SpieringsAE> s/that/that has/g

18:49 <SpieringsAE> didn't find any documentation that specifies it though in this time

18:50 <konradybcio> both dtc and the syntax spec are a bit too loose in my opinion

18:51 <travmurav[m]> well not like it can do much unless you make it tap into dt bindings

18:51 <travmurav[m]> and even that I guess we don't have good formal documentation for non-spec things

18:52 <SpieringsAE> is there any documentation about what that #size-cells etc means? I've never fully understood what it means

18:52 * travmurav[m] should admit that he took way too long to realize "#" just shorthands to "№"

18:53 <travmurav[m]> size/addr ones are actually well defined by libfdt

18:54 <travmurav[m]> https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#address-cells-and-size-cells

18:55 <travmurav[m]> I guess interrupt-cells in the same spec defines general idea how most other ones are used

18:55 <SpieringsAE> Nice! thank you, that is a good thing for me to read thouroughly

18:56 <travmurav[m]> ah, 2.5.1.4

18:56 <travmurav[m]> I guess the whole chapter 2.5
